Maintenance
Battery Replacement
This watch uses an SR920SW style battery, providing approximately 2 years of life. When the watch stops or the hands move erratically, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
Cleaning and Care
- Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture.
- For the stainless steel band, use a soft brush and mild soapy water to clean, then rinse thoroughly with fresh water and dry completely.
- Avoid exposing the watch to extreme temperatures, direct sunlight for prolonged periods, or strong magnetic fields.
Water Resistance (100M / 10 ATM)
The watch is water resistant to 100 meters (10 ATM), suitable for everyday use, swimming, and snorkeling. It is not suitable for diving. Ensure the crown is pushed in completely before any contact with water. Do not operate buttons or the crown while the watch is wet or submerged.
